Specication of Letters Patent. i

Serial No. 659,609.

To all whom t may concern:

Be it known that I, EARLEY W. RICE, a citizen of the United States, residing at Waxahachie, in the county of Ellis and State of Texas, have invented certain new and useful Improvements in Furnaces, of which the following is a specication.

My invention relates to furnaces and particularly to furnaces for heating boilers, and the object is to provide a furnace which will consume all the products of combustion in the fuel. l

. The improved furnace is particularly adapted for burning lignite and other low grades of fuel and coal. The furnace is provided with means for retarding the draft which is carrying the products of combustion through the furnace and also for scattering the products of combustion at several points in the furnace.

Other obj ects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawing which forms a part of this application.

Figure 1 is a longitudinal section of a furnace showing a boiler mountedover the furnace. Fig. 2 is a vertical section on the line -m of Fig. 1. Fig. 3 is a vertical section on the line 2-2 of Fig. 1. Fig. 4 is a` doors 7 The fire box is provided with gratey bars 6.which are supported in the front wall and in a baiile wall9. The baflle wall 9fhas perforations 10 for scattering the draft of gases and smoke passing from the fire box.

The smoke and other gases next come in contact with the walls 11 of a heating chamber 12. The front part of theA wall S11 has projecting blocks or `lugs 13 for breaking up the draft of combustion products.- The front wall 11 also has perforations 17 and 18 yfor the passage of the products of combustion into the chamber 12. The chamber 12 has a baliie wall 19 therein which is perforated for further disintegration or scattering of the products of combustion. The greater portion of the products of combustion passes over the top of the Wall 19 and then downwardly.y All the products of combustion not consumed would pass out through the perforations 16 and would be consumed before the escape from the furnace.

I claim as new and desire to secure by Letters Patent, is,- g

1. A furnace having a front wall and a lheating chamber transversely arranged in the furnace, said wall and said heating chamber being adapted to support a boiler in the upper part of the furnace, a bafde wall within said furnace and forming with the front wall thereof a fire box and having perforations through the upper part thereof, said heating chamber being spaced from said baffle wall and having its front and rear walls perforated, and a baffle wall within said heating chamber and having perforations therethrough arranged in staggered relation to the perforations through the front and rear walls of the heating Chamber, a passage being formed between the baffle wall and the front wall of the heating chamber and over the top of the baffle wall and down between the baiiie wall and the rear wall of the heating chamber to the perforation through the rear wall.V

2. A furnace having `a front wall and a heating chamber transversely arranged in the furnace, said wall and said heating chamber being adapted to support a boiler in the upper part of the furnace, a baffle, `wall within saidfurnace and forming with the front wall thereof a fire box, grate bars in said fire box, said baille wall being perforated at the upper part thereof and forming with said heating chamber, a heating Having fully described my invention what zone within the furnace, said `heating chamber having the front and rear walls thereof perforated and a series of scattering members projecting from the front wall thereof into said heating zone, a baie wall within said heating chamber, a passage being formed between the baffle wall and the front the presence of two witnesses, this 17th day wall thereof and over the top of the baffle of October, 1911. wall and down between the bafe wall and the rear wall of the heating Chamber to the EARLEY W' RIGE perforation therethrough, and suitable doors Witnesses:

for said furnace. A. L. JACKSON,

' In testimony whereof, I set my hand in J. W. STITT.
